Joyce baked a cake using 2 3/4 cups of brown sugar and 1 3/4 cups of powdered sugar. How many cups of sugar did she use in her c

BartSMP [9]

So she has used two kinds of sugar, brown and powdered.

She used $2 \frac{3}{4}$ cups of brown sugar and $1 \frac{3}{4}$ cups of powdered sugar: we need to add the two numbers:

$2 \frac{3}{4}$ + $1 \frac{3}{4}$ = 2+1+ $\frac{3}{4}+ \frac{3}{4}$ =3 $\frac{6}{4}=3+1+ \frac{2}{4} =4 \frac{2}{4}=4 \frac{1}{2}=4.5$

so the correct answer is 4.5

The equation of line t is y = -2x + 9. Perpendicular to line t is line u, which passes through

Archy [21]

Answer:

Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$

Step-by-step explanation:

Equation of line t : y = -2x + 9.

We need to find equation of line u, which is perpendicular to line t and passes through point (-10,4)

The equation must be in slope-intercept form.

The general equation of slope-intercept form is: $y=mx+b$ where m is slope and b is y-intercept

Finding Slope:

If two lines are perpendicular, their slopes are opposite i.e $m=-\frac{1}{m}$

Slope of line t: y=-2x+9 we get m =-2 (Comparing with general form y=mx+b, we get m =-2)

Slope of line u: $\frac{1}{2}$

So, we get Slope of line u: m= $\frac{1}{2}$

Finding y-intercept:

Using slope m= $\frac{1}{2}$ and point(-10,4) we can find y-intercept

$y=mx+b\\4=\frac{1}{2}(-10)+b\\4=-5+b\\b=4+5\\b=9$

Equation of line u:

So, equation of line u, having slope m= $\frac{1}{2}$ and y-intercept b=9, we get:

$y=mx+b\\y=\frac{1}{2}x+9$

So, Equation of line u in slope-intercept form is: $\mathbf{y=\frac{1}{2}x+9 }$

Solve the question below.<br><br> A. 3<br> B. 7.5<br> C. 4.5<br> D. 6

Otrada [13]

Answer:

3

Step-by-step explanation:

Triangle ABO is a right triangle, and so we can use the Pythagorean Theorem to find the radius, r:

r² + 6² = 7.5², or r² = 56.25 - 36 = 20.25

Taking the square root of both sides yields r = √20.25 = 4.5.

If the radius is 4.5, then subtracting this from 7.5 yields 3, the distance between point A and the rim of the circle.

The desired distance is 3 (Answer A).
